Abstract
The invention relates to a filling valve for dispensing a fluid, comprising an inlet opening for connecting to a fluid supply line, an outlet end (12) which lies opposite the inlet opening, a main valve for controlling the flow of the fluid through the filling valve, and a leakage protection valve (13) which is arranged downstream of the main valve, comprising a valve seat (14) and a valve body (15, 16) which can be moved into a closed position in an upstream direction. According to the invention, the valve body (15, 16) has a first sub-body (15) and a second sub-body (16) which is designed to be movable relative to the first sub-body, wherein a first fluid path (17) can be released by a movement of the first sub-body (15) in a downstream direction relative to the valve seat (14), and a second fluid path (18) can be released by a movement of the second sub-body (16) in a downstream direction relative to the first sub-body (15). By virtue of the two-part valve body according to the invention, the flow of fluid through the filling valve can be optimized and the back pressure accumulating in front of the leakage protection valve can be reduced.
Claims (16)
1. Filling nozzle for dispensing a fluid, comprising; an inlet opening for connection to a fluid feed line, an outlet end situated opposite the inlet opening, 5 a main valve for controlling a fluid flow through the filling nozzle, and a discharge protection valve arranged downstream of the main valve and having a valve seat and having a valve body which is movable upstream into a closed position, wherein 10 the valve body has a first part-body and a second part- body, which is configured to be movable relative to the first part-body, wherein, by way of a downstream-directed movement of the first part-body relative to the valve seat, a first fluid path is able to be opened up, and 15 wherein, by way of a downstream-directed movement of the second part-body relative to the first part-body, a second fluid path is able to be opened up, and wherein one of the first and second part-bodies is configured such that, during a movement in a direction of the closed position, it 20 carries the other one of the first and second part-bodies along into the closed position.
2. Filling nozzle according to claim 1, in which the first part-body has at least one passage opening for the second fluid path, wherein the at least one passage opening is 25 able to be opened up by way of the movement of the second part-body relative to the first part-body.
3. Filling nozzle according to claim 1, in which the second part-body has a sealing surface for abutment against a counterpart sealing surface of the first part-body, wherein 20006350_1 (GHMatters) P118722.NZ the counterpart sealing surface forms a part-body valve seat for the first part-body.
4. Filling nozzle according to claim 3, in which the sealing surface of the second part-body and the counterpart sealing 5 surface of the first part-body assume an angle of between 60° and 120° to an axial direction of the discharge protection valve.
5. Filling nozzle according to claim 3, in which the second part-body has a circumferential surface which, in the 10 closed position of the discharge protection valve, is radially completely surrounded by the first part-body.
6. Filling nozzle according to claim 5, in which the second part-body, proceeding from the sealing surface, narrows in cross section towards an inlet-side end, wherein an outer 15 surface of the second part-body has in a region of a narrowing a first portion and a second portion, which is arranged upstream of the first portion, wherein the first portion is outwardly bulged and the second portion is inwardly bulged. 20
7. Filling nozzle according to claim 5, wherein the second part-body is arranged concentrically with respect to the first part-body.
8. Filling nozzle according to claim 1, in which at least one of the first and second part-bodies is guided with sliding 25 action relative to the valve seat by means of a linear guide, wherein the linear guide has a shank which extends in an axial direction of the discharge protection valve and which is guided with sliding action through a passage opening of the second part-body, 30 and/or 20006350_1 (GHMatters) P118722.NZ has a registration opening which is arranged rigidly relative to the valve seat and through which a guide limb of the first part-body is guided with sliding action.
9. Filling nozzle according to claim 1, in which the first 5 part-body has at least one guide web on which the second part-body is guided with sliding action.
10. Filling nozzle according to claim 1, in which the second part-body is configured such that, during a movement in the direction of the closed position, it carries the first 10 part-body along into the closed position, wherein the carrying-along of the first part-body is realized by a transmission of force from the sealing surface of the second part-body to a counterpart sealing surface of the first part-body. 15
11. Filling nozzle according to claim 10, having a mechanical restoring element which is configured to force the second part-body into the closed position.
12. Filling nozzle according to claim 10, in which the second part-body comprises a magnetic material, and provision is 20 made of a counterpart magnet body which is arranged upstream of the second part-body and which is configured to hold the first and second part-bodies in the closed position of the discharge protection valve by way of magnetic interaction, wherein the first part-body is formed 25 from a non-magnetic material.
13. Filling nozzle according to claim 12, in which the second part-body has a maximum open position which is situated outside an effective range of the counterpart magnet body, with a result that, after a fluid-dispensing process has 30 ended, the second part-body remains in an open position, 20006350_1 (GHMatters) P118722.NZ wherein, through utilization of gravitational force, the second part-body is able to be moved back into the effective range, within which said second part-body is drawn into the closed position by the counterpart magnet 5 body if the filling nozzle is inclined upwardly on a discharge side.
14. Filling nozzle according to claim 1, in which the discharge protection valve is arranged on an inlet end of a discharge pipe of the filling nozzle. 10 15. Discharge pipe for a filling nozzle for dispensing a fluid, comprising: an inlet end connectable to a housing of the filling nozzle, an outlet end situated opposite the inlet end, and
15.a discharge protection valve having a valve seat and having a valve body which is movable upstream into a closed position, wherein the valve body has a first part-body and a second part-body, which is configured to be movable relative to the first part-body, wherein, by way of a 20 downstream-directed movement of the first part-body relative to the valve seat of the discharge protection valve, a first fluid path is able to be opened up, and wherein, by way of a downstream-directed movement of the second part-body relative to the first part-body, a second 25 fluid path is able to be opened up, wherein one of the first and second part-bodies is configured such that, during a movement in the direction of the closed position, it carries the other one of the first and second part- bodies along into the closed position. 20006350_1 (GHMatters) P118722.NZ
16. Discharge pipe according to claim 15, wherein the discharge protection valve is arranged on the inlet end of the discharge pipe.
